The skill I was learning was a crucial one, the patience to read things I could not yet understand. - Tara Westover

I began to study trigonometry. There was solace in its strange formulas and equations. I was drawn to the Pythagorean theorem and its promise of a universal—the ability to predict the nature of any three points containing a right angle, anywhere, always. What I knew of physics I had learned in the junkyard, where the physical world often seemed unstable, capricious. But here was a principal through which the dimensions of life could be defined, captured. Perhaps reality was not wholly volatile. Perhaps it could be explained, predicted. Perhaps it could be made to make sense.

We had been bruised and gashed and concussed, had our legs set on fire and our heads cut open. We had lived in a state of alert, a kind of constant terror, our brains flooding with cortisol because we knew that any of those things might happen at any moment. Because Dad always put faith before safety. Because he believed himself right, and he kept on believing himself right—after the first car crash, after the second, after the bin, the fire, the pallet. And it was us who paid.

By the end of it, I had finally begun to grasp something that should have been immediately apparent: that someone had opposed the great march toward equality; someone had been the person from whom freedom had to be wrested.
